Title: Inner ear diagnostic apparatus and method
Inventor: BRAINARD EDWARD C II
IPC: A61B1/227
Filed: 1997-11-25
Abstract: A system and method for measurement of ear conditions utilizing a test signal. The apparatus includes a wave guide (16) having a proximal and distal end. The distal end is connected to a probe tip (18), which may be fabricated of a semirigid material or rigid material and may further be a material transmissive light. The probe tip (18) is sized so as to fit at least a portion of the probe tip (18) within the ear canal (38). The wave guide (16) further includes an acoustic energy source (14) disposed substantially at the proximal end for generating a test acoustic wave in response to a source signal. The wave guide (16) further includes an acoustic energy detector, for example a microphone (20), for detection of reflected acoustic energy and generation of an electrical signal in response. The apparatus is controlled by a processor. The processor is adapted to generate the source signal which will preferably contain pseudo-random noise. The processor is further adapted to receive the detected signal from the acoustic energy detector and to generate a condition signal related to the ear condition in response to the detector signal and the source signal. The condition signal may be utilized to control a video display (43), a printout device (44), or any other device capable of conveying to the operator the ear condition. The apparatus may be further adapted to view the ear while testing by including a lens (22) at the proximal end and a light source (24) toward the distal end of the wave guide (16). Also disclosed is a method for measurement of ear conditions.

Abstract: Determining the location of a wireless terminal and provides access to data stored in a database of a central computer associated with that location to the wireless terminal. The user of the wireless terminal is not required to perform any activity to gain access to data associated with the location. The degree of access to the data associated with a location is dependent upon the authorization information supplied by the wireless terminal to the central computer after the location of the wireless terminal has been determined. In addition, the wireless terminal may be a computer capable of wireless communication, a wireless PDA, or a wireless telephone set having display and data entry capabilities. In a first embodiment, a wireless terminal communicates with the central computer via a wireless switching system. The central computer determines the location of the wireless terminal upon establishment of a communication path between the wireless terminal and the central computer. In a second embodiment of the invention, the wireless terminal communicates via a wireless transceiver with the central computer. There is one wireless transceiver for each location. The transceivers are connected to the central computer by a local area network (LAN).

Patent CA-2282222-A1 (CA)
Inventor: HUMPHREY LESLEY DEREK
IPC: H04L5/14
Filed: 1999-09-15
Abstract: To alleviate the requirement to back-off all up-link performance, such as by limiting power spectral density, to overcome far-end cross-talk problems otherwise associated with relatively short loop-length wireline links, the present invention partitions the frequency spectrum based on an estimate of the loop length of a subscriber unit (CPE) modem from an exchange (LTE) modem. Up to a threshold frequency (f max) at which received transmissions from a subscriber having a longest loop length (115) become indistinguishable by the LTE modem from a noise floor (102), up-link performance on all loop lengths is limited to correspond to that of the longest loop. At frequencies above the threshold frequency (f max), subsets of subscribers (152-154) having relatively short loop lengths (116-119) use high frequency carriers that have signal to noise ratios sufficient to support information transmission in these elevated frequency bands. Within each subset of subscribers, backing-off of performance to that of the longest loop length within the subset is, however, necessary to avoid FEXT, as shown in FIG. 4. The higher frequency bands are used to support up-link transmission complementary to or mutually exclusive with up-link transmissions using frequencies below the threshold frequency (f max) and so, respectively, provide increased channel capacity or reduced cross-talk.

Abstract: Rather than relying solely on a public-switched network (PSN) in order to leave a voice-mail message when a callee is not available take a call from a caller, communications are transferred to a packet-switched network, such as the Internet, and the voice-mail message from the caller to the callee is transmitted over the packet-switched network. For long-distance and other time-based toll calling, cost savings are provided as compared to conventional PSN-based voice-mail schemes in which the entire time that it takes to leave a voice-mail message is charged to either the caller or the callee on an incremental cost basis.

Abstract: True body composition is estimated using a dual-energy, fan-shaped distribution of x-rays and signal processing that corrects for mass magnification and other effects due to the geometry of the measurement system. To avoid inaccuracies due to beam hardening and certain other effects, the thickness of attenuating material along respective raypaths is obtained through using a four-dimensional look-up table derived experimentally from step-wedge measurements. To correct for mass magnification effects due to using a fan-shaped distribution of x-rays, another look-up table and interpolation between table entries are used to convert projected mass to true mass.

Title: Particulate trap for diesel engines
Inventor: OJI MASATAKA
IPC: F01N3/24
Filed: 2000-06-27
Abstract: A particulate trap that burns and removes particulate matters (particles, consisting mainly of carbon particles, contained in the exhaust gas of a diesel engine of a car) trapped by a filter without using a specifically provided heat source such as a burner or an electric heater even when the car is running in ordinary urban areas, i.e., when the exhaust gas is low in temperature. In the particulate trap, a catalytic converter 3, formed of a metallic porous body hav-ing a three-dimensional network structure, carrying an oxidizing catalyst is placed upstream of a filter 4 that traps particulate matters. The catalytic con-verter 3 oxidizes NO in the exhaust gas into NO2, which in turn burns and re-moves particulate matters trapped by the filter 4.
